Explanation:

The word dismantle means to take something apart, destroy its structure, or break it into pieces.

In simple words: to break down something that was built.

The opposite of dismantle is build, which means to construct, assemble, or create something step by step.

So, Build is the correct antonym of Dismantle.

Real-Life Example

Imagine a house:

• Workers break down an old house → this is dismantling.
• Workers construct a new house → this is building.

Break down = Dismantle
Construct = Build
